SINK. OR ANALOGOUS ARTICLE.

SPECIFICATION forming part of Letters Patent No. 297,404, dated April 22, 1884.

Application lcd October $20, 1883. (No model.)

To all whom, t may concern:

Be it known that I, HENRY L. JAooBs, of Columbus, in the county of Franklin and State of Ohio, have invented a certain new and use ful Improvement in Sinks and Analogous Articles, of which the following is a specification.

This in'1prove1nent,while designed more particularly for use in sinks, is also applicable to stationary wash-bowls, tanks, and the like pro vided with lead wastepipes' and strainers, and I desire to be understood as including this application in my claims.

The improvement is directed to means for more conveniently and securely attaching' the pipe to the neck ofthe sink, and also to means for holding in place the strainer, which usually is placed in or on the bottom of the sink,over the pipe or opening leading thereto. Under my improvement I insert the pipe into the neck, and then drive into the upper end of the pipe a tubular ferrule of externally conical or tapering form, which acts as a wedge or expanding device to spread the upper end of the pipe and to clamp or bind it with the utmost security and tightness in place in the neck, the joint at the top being calked, in the manner well known to plumbers, by hammering down the projecting upper end of the pipe upon and around the upper end of the plug, which for this purpose has an external bevel. In this way the neck, the pipe, and the plug are held securely together. The ferrule or plug thus placed serves as a convenient means by which the strainer-plate can be held in place. For this purpose it is provided with a screw-threaded hole for reception of a binding-screw, which, afterthe strainerplate is put in position over the opening in the sink, is inserted through a suitable hole in the plate, and is screwed down into the plug or ferrule. The parts are thus' attached with simplicity and ease, there can be no leakage, and the strainer can be easily removed to clean the pipe.

The nature of my invention and the manner in which the same is or may be carried into effect will be readily understood by reference to the accompanying drawings, in which- Figure l is a sectional perspective view of a sink embodying my improvement, the` line of section passing vertically and axially through the neck. Fig. 2 is a perspective view of the ferrule or plug detached. Fig. 3 is a like view of a modification hereinafter referred. to.

A is the sink, and Bl is the neck thereof. Thelower tubular portion of the neck B is by preference slightly tapering or conical, as seen at a.

C represents the lead pipe, which is to be connected to the neck B.

D is the tubular ferrule or plug by which the pipe is fastened in place.

The upper end of the pipe is iirst inserted in the part c of the neck. Vhile the pipe is in this position the plug D, which has a somewhat tapering form, preferably as shown, is inserted into it from above, and is then driven down into the neck, thus expanding and spreading the pipe against the flaring walls of the neck, and making a thoroughly. tight and secure joint between the two. In practice the pipe'is inserted to such an eX- tent' in the neck that when the plug or ferrule is driven home the pipe will extend about a quarter of an inch above it. rIhis protruding portion of the pipe' is calked down so as to lap over upon the beveled upper portion, b, of the plug. This completes the operation.

The pipe is held tightly, firmly, and immovably in place, and the joint is entirely secure against leakage. As hereinbe'i'ore stated, the plug D thus placed can be conveniently used as a means to hold the strainer in place. w For this purpose the plug, which preferably is made of malleable iron, is formed or provided on top with a screw-threaded hole or socket to receive the binding-screw. of the strainer-plate. This socket can occu py any suitable position inthe plug. It may, for instance, be made by providing the plug with a cross-bar, c, and by tapping therein a screw-threaded hole, d.

rIhe strainer E is provided with a suitable hole, e, which, when the strainer is in place, stands vertically above hole d, and a screw, f, passing freely through hole c and screwed down into hole Z in the cross-bar until its head brings up against the strainer, holds the latter securely in place, being at the same time readily removable, so that the strainer can conveniently be taken o whenever itis de- IOO sired to get at the plug or pipe below for uny purpose.

In lieu of making use of u crossbur7 c, the hole can he tapped in u lug` or eur, c', of the plug, as indicated at cl, Fig. 3. Thelutter is the arrangement which, on the whole, I prefer.

At whatever point the hole is formed, the binding-screw e Will of course pass through the strainer ut :t point over the said hole.

Having now described my improvement and the best way known to Ine of carrying the same into effect, what I claim as new and of my own invention is as follows:

1. The combination of `the sink-neck, the expanding,` plug or ferrule, and the pipe expanded und clamped against the interior walls of the neck by the ferrule, end calked down around and upon the upper portion of the HENRY L. JACOBS.
